Nadiya Hussain takes a culinary road trip through Scotland, joining professional forager Gary Goldie at Airds Bay in Argyll and Bute to pick hogweed and sea arrowgrass to use as flavourings for a wild curry. She then heads to the Cairngorms National Park to visits the Blair Atholl watermill run by baker Rami Cohen, grinding her own flour to bake Indian five-spice soda bread, served with a red lentil dish. Back in her kitchen, Nadiya creates a vegetarian haggis tarte Tatin.
